Brakes:
When the current is cut, the electromagnetic attractive force disappears.
The brake spring (8) pushes the pressure disc (6) back on the brake disc
(1-2). This closes the brake.
Releasing the brake:
When the brake coil (7) is energized, the pressure disc (6) is attracted and
the brake pressure spring (8) is pressed in. By this, the brake discs (1 and
2) open up.
Brake clearance:
Check the brake clearance for soiling (oil - grease). Normal brake
clearance is 0.8 to 1.2 mm.
Brake moment adjustment:
Factory-set
Releasing the brake manually:
The brake can be released manually by loosening the brake yoke (9 and
10).
ATTENTION: Working with a manually released brake is not
permitted.
